In later papers we have shown that sunward, generally dark, plasma features which are originated above posteruption flare arcades are consistent with a scenario where plasma voids are generated by the bouncing and interfering of shocks and expansion waves upstream of an initial localized deposition of energy which is collimated in the magnetic field direction. In this paper we analyse the multiple production and interaction of supra?arcade downflows (SAD) and the structure of individual SADs that make them relatively stable features while they move. We compare our results with observations and with the scenarios proposed by other authors.
